Overview
The FOD8480R2 is a high-speed logic gate optocoupler produced by onsemi. It is designed to provide an isolated interface for communicating digital control signals, particularly between a controller and an Intelligent Power Module (IPM). This optocoupler ensures the isolation of ground loops and hazardous voltages, making it suitable for various industrial and power management applications. The device is packaged in a 6-pin small outline plastic package (SOIC-6) and features an aluminum gallium arsenide (AlGaAs) light emitting diode and an integrated high gain photo detector with hysteresis for noise immunity.
